8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TPD1E1B04 is a diode type TVS which is used to provide a path to ground for dissipating ESD events on

high-speed signal lines between a human interface connector and a system. As the current from ESD passes

through the TVS, only a small voltage drop is present across the diode. This is the voltage presented to the
